Here’s another Eberspacher control unit, this time from an ancient D5W 5kW water heater. The system in this case is just flaky – sometimes the heater will start without fault & run perfectly, then suddenly will stop working entirely. The error codes are read on these very old units via
It’s that time again, so the boat is out of the water for it’s 3-yearly maintenance. Some things over the past few months have been bugging me, namely a pronounced vibration in the running gear while underway. (Issue was easy to spot here!). nb Tanya Louise being a very odd
Here’s a novel little gadget, a USB powered soldering iron. The heating tip on these is very small & might be useful for very small SMD work. Bigger joints not so much, as it’s only rated at 8W. (Still breaks the USB standard of 2.5W from a single port). These
Magnetic tape is the medium of choice for my offline backups & archives, as it’s got an amazing level of durability when in storage. (LTO Has a 30 year archival rating). For the smaller stuff, like backing up the web server this very site runs on, another format seemed to
In my mind, the most dangerous thing onboard any boat is the LPG system, as the gas is heavier than air, any leaks tend to collect in the bilges, just waiting for an ignition source. To mitigate this possibility, we’re fitting a gas monitoring system that will sound an alarm
Here’s a rather unique device for protecting safes & vaults from attack by thefts. It’s an Aritech VV602 seismic detector, based on piezoelectric sensors. Not surprisingly, this unit is covered in tamper sensors as well. There are several different sensor types in use: Piezoelectric vibration sensing Thermal sensing Magnetic sensing
To accompany the previous two posts about hydraulic generators & their components, here is the actual generator unit itself. Rated at 8.5kVa 230v AC, this will providea mains supply while the narrowboat is away from her home mooring. This unit will be attached to the side of the hull in
Here is a more modern phone, the Motorola V360v. Features include Dual screens, 640×480 VGA camera, full col our TFT Main LCD, SD-Micro slot. Here on the back the grey scale LCD can be seen, with the camera lens to the right of the Motorola logo Here the phone is
Another phone from the mid 90s. This is the nokia 7110. Here the slider is open showing the keypad. Here the battery is removed, a Li-Ion unit. The battery cell & protection circuit removed from the casing. This is the rear of the PCB removed from the housing. Data &
